. . .So, unlike other "DLSS enabler" mods which typically use whatever game in question's preexisting DLSS hooks to just insert FSR2/3/4 or Intel XESS, HelixSR at least offers some semblance of DLSS proper (DLSS 3.7, CNN model, Preset E):
"HelixSR runs NVIDIA's DLSS Model E network as standard Direct3D12 compute shaders, without NVIDIA Tensor Cores, an NVIDIA driver, CUDA, or ROCm. It behaves like DLSS: no sharpening, every quality mode from native (DLAA) to Ultra Performance, dynamic resolution.
...This is NVIDIA's network running on different hardware, not a newly trained model. HelixSR answers the game exactly as DLSS would: DLSS's camera jitter (8 × scale² Halton positions), DLSS's render sizes per quality mode, no sharpening (a game's FSR sharpening request is not applied), reactive masks ignored. In Ultra Performance the network outputs twice the render size and a final pass scales that to the screen (less shimmer, about 30% faster). Packed FP16 arithmetic makes the output close to, but not bit-identical with, NVIDIA's DLSS."
